あたし的には, 2.x 系ででてるけど, それだけではないのか.

java.lang.NoClassDefFoundError: android/os/AsyncTask - Google グループ

Issue 81083 - android - java.lang.ClassNotFoundException: android.os.AsyncTask caused by AdMob / Google Play Services - Android Open Source Project - Issue Tracker - Google Project Hosting

解決方法としては以下が挙げられてる.

try
{
Class.forName("android.os.AsyncTask"); //it prevents AdMob from crashing on HTC with Android 4.0.x
}
catch(Throwable ignored)
{}

The AsyncTask class must be loaded on the UI thread. This is done automatically as of JELLY_BEAN.

これはどこがアナウンスするべきなのだろうか.

他にもいろいろあるような気もするけども.
